It first proposes a statistical segmentation model integrating the simplified character juncture model (SCJM) with word formation power. The advantage of this model is that it can employ the affinity of characters inside or outside a word and word formation power simultaneously to process disambiguation and all the parameters can be estimated in an unsupervised way. After investigating the differences between real and theoretical size of segmentation space, we apply A * algorithm to perform segmentation without exhaustively searching all the potential segmentations. Finally, an unsupervised version of Chinese word formation patterns to detect unknown words is presented. Experiments show that the proposed methods are efficient.展开更多

In order to study seafarers’ fatigue, a questionnaire-base survey was conducted to gain information about potential risk factors for fatigue and construct indexes indicating fatigue. The study applies T-test to compare strata of seafarers to analyse work and sleep patterns in global seafaring. Qualitative analysis are also employed to explore the impacts of fatigue on seafarer’s occupational health and safety.展开更多
